The upper surface and the lower surface of the unidirectional wheel body 3.1 are respectively connected with a sealing ring 3.5, and the sealing rings 3.5 are fixed on the unidirectional wheel body 3.1 through bolts, so that the rolling elements 3.3 and the elastic parts 3.4 are sealed in the triangular grooves 3.6, and the rolling elements 3.3 are prevented from being extruded in the rotating process. Alternatively, the rolling elements 3.3 may be steel cylinders or steel balls, and the height of the cylinders and the diameter of the balls are smaller than the thickness of the unidirectional wheel body 3.1, so that the rolling elements 3.3 are installed in the triangular grooves 3.6; the elastic part 3.4 is a metal spring or the like, and has the main function of being matched with the rolling part 3.3 to realize unidirectional rotation of the unidirectional wheel body 3.1, and only the outer gear ring 3.2 slips on the unidirectional wheel body 3.1 during reverse movement, so that the unidirectional wheel body 3.1 cannot be driven to reversely rotate.
Taking fig. 3 as an example, when the gear overrunning mechanism 3 with this structure is used in the part peripheral surface machining device of this embodiment, when the outer gear ring 3.2 is driven by the driving mechanism 8 to rotate anticlockwise, the rolling member 3.3 is pushed forward by the friction force of the inner wall of the outer gear ring 3.2 to the included angle between the triangular groove 3.6 and the inner wall of the outer gear ring 3.2, so as to drive the unidirectional wheel body 3.1 to move together, so that the spindle 2, the gear overrunning mechanism 3, the locking wheel 4, the ratchet wheel 5 and the tray 6 rotate together with the whole formed by the part 21 to be machined, and the rotation angle (indexing) is controlled by the set travel of the driving mechanism 8. When the driving mechanism 8 returns, the outer gear ring 3.2 rotates reversely, the rolling element 3.3 is pressed backwards to the elastic element 3.4 under the friction force of the inner wall of the outer gear ring 3.2, the elastic element 3.4 is compressed, the unidirectional wheel body 3.1 is separated from the outer gear ring 3.2, only the outer gear ring 3.2 rotates reversely on the unidirectional wheel body 3.1, and the unidirectional wheel body 3.1 is not carried to rotate reversely, so that the position of the part 21 to be machined, which is already at the completion of indexing, is prevented from being changed, and the indexing failure is caused.
The pawl 7 is rotatably connected to the rotating shaft 18, one end of the pawl 7 is connected to a tension spring 19 connected to the side plate 14, and the other end of the pawl 7 abuts against the wheel surface of the ratchet wheel 5 under the action of the tension spring 19, that is, the pawl 7 is kept in elastic contact with the ratchet wheel 5.
The driving mechanism 8 is a linear driving mechanism, such as a cylinder or a linear direct-drive motor, so as to drive the outer gear ring 3.2 to rotate. Further, one end of the drive shaft of the drive mechanism 8 is connected to a rack 15, which rack 15 meshes with the external teeth of the external gear ring 3.2. The rack 15 is slidably connected to the guide groove 16, and the guide groove 16 is fixed to the side plate 14. The driving mechanism 8 is provided with a position sensor 17 so as to collect position information of the driving mechanism 8, and then the travel of the driving mechanism 8 is controlled by a controller.
The locking hook 9 is fixed at the other end of the rack 15, and when the return stroke of the driving mechanism 8 is finished, the locking hook 9 is just clamped into the first clamping groove 10 of the locking wheel 4, the pawl 7 is clamped into the second clamping groove 11 of the ratchet wheel 5, and the opposite side of the first clamping groove 10 is always provided with the second clamping groove 11, so that the whole locking and positioning formed by the mandrel 2, the gear overrunning mechanism 3, the locking wheel 4, the ratchet wheel 5 and the tray 6 is realized, and the whole rotation is avoided when the part fixed on the tray 6 is cut, so that the damage of a cutting tool is caused, and the processing of the peripheral surface of the part is influenced.
The number of the second engaging grooves 11 on the ratchet wheel 5 is the same as the number of the flat surfaces to be machined on the outer peripheral surface of the part, and the second engaging grooves 11 are uniformly distributed on the wheel surface of the ratchet wheel 5. Similarly, the number of the first clamping grooves 10 on the locking wheel 4 is the same as the number of the planes which need to be processed on the outer peripheral surface of the part, and the first clamping grooves 10 are uniformly distributed on the wheel surface of the ratchet wheel 5.
In this embodiment, the number of the second clamping grooves 11 on the ratchet wheel 5 and the number of the first clamping grooves 10 on the locking wheel 4 are two, the outer peripheral surface of the corresponding part 21 to be processed is processed into two flat surfaces, and each time the ratchet wheel 5 rotates 180 °, the pawl 7 enters one second clamping groove 11. For another example, when the outer peripheral surface of the disc part needs to be processed into a tetrahedron, four second clamping grooves 11 are uniformly distributed on the wheel surface of the ratchet wheel 5, and each time the ratchet wheel 5 rotates 90 degrees, the pawl 7 enters one second clamping groove 11, at this time, the ratchet wheel 5 cannot move reversely, and the locking wheel 4 cannot move reversely, so that the gear overrunning mechanism 3, the locking wheel 4, the ratchet wheel 5 and the tray 6 form an integral locking position, and cannot rotate.
Taking disc-like parts as an example, when the outer peripheral surface of the parts is processed by the processing device, the basic process is as follows: the whole processing device is fixed on a sawing machine or a milling machine by bolts from a fixing plate 1 so as to cut the peripheral surface of the part by using a saw blade or a milling cutter. Then, after the disc type part 21 to be machined is sleeved on the mandrel 2 and is fixed with the mandrel 2 into a whole through the part pressing plate 20, the driving device 8 is started to complete a stroke, the gear overrunning mechanism 3 is driven to rotate anticlockwise by an angle, the driving device 8 returns to enable the position of the part 21 to be machined, which is already in indexing completion, to be locked, the part to be machined is cut downwards by the saw blade, a machining surface is obtained after completion, then the driving device 8 continues to drive the gear overrunning mechanism 3 to rotate 180 degrees, indexing of the part 21 to be machined is completed, the driving device 8 returns to enable the position of the part 21 to be machined to be locked, and the saw blade cuts the part to be machined to complete machining of the other surface. It can be seen that the part peripheral surface machining device skillfully utilizes the linkage among the gear overrunning mechanism 3, the locking wheel 4, the locking hook 9, the ratchet wheel 5, the pawl 7 and the driving mechanism 8, and realizes the continuous machining and the accurate indexing of the part peripheral surface, because the gear overrunning mechanism 3 can realize the rotation of a set angle under the driving of the driving mechanism 8, the automatic indexing of the part to be machined can be completed by utilizing the rotation of the gear overrunning mechanism 3, the degree of automation is high, and the indexing is accurate. Meanwhile, by utilizing the arrangement of a specific position between the locking wheel 4 and the ratchet wheel 5, utilizing the locking hook 9 to lock the locking wheel 4 in the positive/reverse direction when the return stroke of the driving mechanism 8 is finished, and utilizing the pawl 7 to lock the ratchet wheel 5 in the reverse/positive direction, the whole locking positioning formed by the mandrel 2, the gear overrunning mechanism 3, the locking wheel 4, the ratchet wheel 5 and the tray 6 is realized, so that the whole rotation is avoided when a part fixed on the tray 6 is cut, the damage of a cutting tool is caused, and the processing of the peripheral surface of the part is influenced. Besides, the characteristic of the gear overrunning mechanism 3 is utilized to avoid the problem that the whole locked and unable to return when the driving mechanism 8 returns, so that the driving mechanism 8 can realize continuous processing and accurate indexing of the peripheral surface of the part only by reciprocating motion, and the problems that the part inconvenient to make two flat surfaces in advance mainly depends on expensive numerical control equipment and manual indexing tools when the part blank is manufactured at present are solved.
